The Influence of Tobacco on Early Dental Implant Failure

PURPOSE The purpose of this study was to assess tobacco use as a risk factor for early implant failure. MATERIALS AND METHODS To address the research aim, a retrospective study design was used, and a study sample was derived from among patients who had 1 or more implants inserted between July 1996 and July 2004. The main predictor variable was the frequency of tobacco use. The major outcome variable was early implant failure. Appropriate descriptive, bivariate, and multivariate statistics were computed. RESULTS The study sample was composed of 650 patients who had 1,628 implants inserted and were selected for analysis. The early implant loss rates found in the nonsmoking group and the smoking group were 3.32% and 2.81%, respectively. Univariate and bivariate analyses showed no statistical significance for early implant losses associated with the frequency of tobacco use. CONCLUSIONS The results of this study suggest that tobacco use alone cannot be considered as a factor for risk related to early implant failures. Prospective studies are needed to assess the risk of early implant failure in conjunction with smoking.

Traumatic Dysgeusia, an Unusual Complication of Facial Trauma: A Case Report.

The chemical senses of taste and smell are important to human life, because they play an important role in detecting potential environmental hazards. Humans can identify countless different flavors by the simultaneous perception of taste and smell. Reports of sensory loss after craniocerebral trauma began to appear in the medical literature in the middle 1800s. Dysgeusia associated with head injuries is rare and its reported incidence is 0.4 to 0.5%. This report describes the clinical case of a 32-year-old man with Le Fort I and III fractures treated with surgical reduction and fixation. The patient presented with dysgeusia after slight improvement of his preoperative anosmia. The prognosis is favorable and the treatment is prospective.

Use of a generic violet light in the surgical management of medication-related osteonecrosis of the jaws: a technical note

PurposeFluorescence-guided surgery has been recommended for the diagnosis of bone margins in cases of mandibular osteonecrosis. In this article, we report a case in which a generic violet light was used in order to activate bone fluorescence after the administration of tetracycline derivatives, as an alternative to a specific, more expensive equipment that is commercially available for this purpose. The patient had been using alendronate for osteoporosis, resulting in medication-related osteonecrosis of the jaws.MethodsThe treatment protocol includes preoperative administration of doxycycline and the application of a generic violet light during surgery in order to observe the fluorescence of bone in response to excitation through the light emitted by this device.ResultsWith an effective visualization of the limit between healthy and devitalized bone tissue, it was possible to perform the necrotic tissue removal. The lesion regressed from stage 2 to stage 0, with no clinical or radiographic evidence of necrotic bone.ConclusionsThese results suggest the feasibility of using a generic violet light source as a low-cost alternative for fluorescence-guided surgery.

Management of Blowout Fracture With Support of Video Endoscopy in a Pediatric Patient.

Pure orbital fractures have the tendency to occur on medial wall and orbital floor; because these points are more fragile, the endoscopy can be utilized for accomplishing the task of repositioning the herniated content, as well as serving as an additional tool, helping to view the orbital defects through a transantral approach. The presented case is a female patient, 12 years old, who was diagnosed as having a pure blowout fracture, on right orbital floor, type trapdoor, with orbital content herniated toward the maxillary sinus. It was realized that a surgical procedure for reduction of orbital content through video endoscopy, via antral, allowed a great viewing of soft and hard structures, checking the positioning of implants and its relation with the orbital cavity, enabling installing through a small surgical access and minimum detachment, and favoring postoperative recovery.

Immediate reconstruction with autogenous graft after removal of recurrent ameloblastoma, treated 8 years previously

Ameloblastoma is the most common benign odontogenic tumor of the jaw, being most frequently found in the mandible, especially in the body and branch regions. The treatment depends on the aggressiveness of the lesion and if not properly treated, can result in significant morbidity. The objective of this study is to report the case of a 29-year-old patient with a history of ameloblastoma which had been enucleated, recurring after 8 years of evolution. The tumor recurrence was treated through mandibular resection and reconstruction with an iliac crest bone graft. The patient is being monitored and is currently post-operative 50 months, showing no signs of recurrence to date. Ameloblastomas are lesions which present unpredictable behavior and thus require close monitoring irrespective of the treatment. Descriptors: Ameloblastoma; Mandibular Neoplasms; Odontogenic Tumors.
